oooo – This one’s tricky! Just ask the students at Whitehorse Elementary!
Get your students to cut apart the number cards (digits ranging from -3 to +5) and have them place them in the magic square cells so that each column, row and diagonal has the same sum.
What’s the sum? Well, there are MANY ways to do this puzzle, so that’s negotiable! This is best done in partners, since two brains are better than one…
Order your digit cards. What do you notice about the number in the middle?
Does that help??
